This session was a hands-on training demonstration on the use of wooden cribbing blocks for rescuing survivors trapped under debris. The training emphasized safety, technique, and the importance of using materials that provide warning before failure.
Okay, today we're going to talk about cribbing and what are our uses for cribbing. We use cribbing and cribbing blocks to rescue a survivor who may be trapped under debris. Before we attempt a rescue, first we're gonna check our victim or our survivor to make sure that they are still alive. So Dan's gonna come around, he's gonna check the airway of our of our survivor. And the way we do that is we open the airway insert, is we open their way twice, and if the patient's still not breathing, we move on. Our goal is to do the greatest good for the greatest number of people. Now, if we open the airway or the patient is conscious, then Dan's gonna communicate with that survivor that we're gonna work on removing them from the debris. It is very labor intensive and is a little time intensive to uh actually build the crib block blocks and maintain safety to remove our survivor. And the way we do that is if you see the way the crippling blocks are placed, they are in the the square. We uh almost like building with Lincoln logs, you put two one direction and then two in the opposite direction, and we build those up. One thing we don't we do not stack on top of each other. If we stack multiple pieces on top of each other, at that point, then they become unstable. That's the reason we only do one in each direction. It gives you more stability. The reason we use wood is wood will give you a warning if it's gonna fail, it's gonna crack, you're gonna hear some noise. Whereas if you use metal or steel, that just fails with no warning. Also, the wood cribbing blocks will hold six thousand pounds on each corner or 24,000 per crib box. And you see how they're built here. We have one on each side, and that's gonna be to stabise the debris as we lift it. In the center, we have a pivot point. This is where we're gonna use our crowbars that can find in the garages, you can find crowbars in various areas. If you don't have a crowbar, you can use a two by fours or other means of uh something that can actually hold that weight to lift it. Now, to reiterate what we've already covered, we use the cribbing blocks out of wood because it gives a warning. You hear a cracking before it fails, or a steel or metal will now give you a warning. Each cribbing block can hold up to 24,000 pounds on each side, and as we lift, we crib from each side to keep everything stable because once we lift, the last thing we want is for that debris to come back down onto our survivor. It is very labor intensive, it is uh very time intensive, so it's not something that happens fast, it does take time to do this to maintain the safety of the survivor as well as your safety. Remember, insert your safety is number one priority. If you're not safe, then you don't attempt the rescue. So we have we started our crib blocks, and now when we go to lift, our leverage point comes from the center here. Usually we use two people to lift, but today we're gonna demonstrate using one, and as he lifts, we're gonna build the crib box on each side to give us the stability that we need. Okay, and as as you can see, as we lift, we may not have total uh we may have some voids areas. We can use wedges that can fill that void. That way, when he lowers, you see there's no movement at all on our debris. And at that point, once the person who's uh maintaining communication with our survivor is able to see that they're clear from that debris and they're able to be slid out at that time. That's when this operation would stop, and now everybody moves over to the survivor to help extricate the survivor from underneath of the debris. When that happens, your your team leader who controls building the cribbing blocks and make sure everybody's safe. Now the person at the head of the survivor now makes all the calls because they're maintaining uh cervical spine on that patient. They're also communicating with that patient, so they're at that point of time, they take over the calls on moving that patient. In most cases, we'll move that patient six inches at a time. And you would need four to six people to move to adequately move the patient out from under the debris. What things you need to watch out for as you're pulling out the survivor is that you don't hit your your crippling blocks because that's your stability. You hit that, that debris come back down to that survivor. So you need to make sure everything's clear prior to moving that victim. What we're gonna demonstrate now is removal of our survivor. In most cases, you would need three, four, or five people to move this patient. But for our demonstration, there's gonna be three of us. Dan's gonna maintain the airway and hold the cervical spine on the patient. He'll make the calls to slide it six inches at a time. And we'll demonstrate that now. And there's some other things I want to narrate as we're moving this survivor.
